Android Web服务无法正常工作

Question

我试图制作一个程序，将带有GCM注册ID的学生注册数据发送到服务器..当我尝试注册用户的父亲名字和母亲名字而没有姓氏时例如：Ajay

和例子

阿杰[空白] Sood

第一个示例中的名称可以在没有空格和姓氏的情况下正常工作。.但是，第二个示例中具有空格的名称则无法工作。

即使我在名字和姓氏之间使用下划线_也可以正常工作。 我不知道怎么了

姓和名之间带有_的logcat文件，例如firstname_lastname，效果很好：

尝试使用以下方法对值进行编码或对完整网址进行编码

    String query = URLEncoder.encode("first name", "utf-8");
    String url = "http://stackoverflow.com/search?q=" + query;

要么

    String encodedUrl = URLEncoder.encode(url, "UTF-8");
